OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 522,087, dated June 26,1894.

Application ilediebrnary 28, 1894. Serial No.50 1.809. (No model.)

oil cans for engines and other machinery.

The object of the invention is to produce a can with which the moreremote points, and points which are least accessible may be readilyreached, and which will deliver the oil positively and in anydesiredquantity.

Another object is to so construct the can that the various parts arereadily accessible and removable for cleaning and repairs.

The invention therefore consists in a can having various novel features,all of which will be fully described in the following speciication, andin connection with the accompanying drawings, in which- Figure l is aview of my improved oil can, the lid and operating partsbeing shown inside elevation, and the body of the canin cross-section. Fig. 2 is asimilar view looking from the left in Fig. 1, and Fig. 3 is a top planview.

Referring to the drawings, A indicates the body or oil receptacle of thecan, and B indicates the lid which is preferably united to the can by ascrew-thread b, an intermediate washer b being used as packing to makethe joint tight. The lid B formsa base upon which all of theoperatingparts of the can are mounted. Beneath the lid and attached thereto inany suitable manner, as by screws, is a pump cylinder C in whichoperates a piston c, the rod of which extends upward through the lid andis surmounted bya thumbpiece c. guide plate D, which keeps it fromturning and in proper relation to the handle a of the can. The piston isnormally kept, at the upper end of its travel by means of a suitablespring, which, as shown, is a plate spring E.

To the lower end of the cylinder is connected a pipe F which has abranch G extending to a point near the bottom of the can where it isprovided with a screen g, and a second branch H extending upward throughThe thumb-piece c works in a the cover and connecting with the spout ofthe can. The branch G is provided with a check-valve g', and a similarcheck valve his placed in the upper branch H. It will be apparent thatwhen the piston is operated the oil will be drawn in through the screeng and pipe G to the cylinder, and thence forced upward through the pipeH to the spout, the cheek valves preventing kit from returning througheither pipe.

Below the cover, upon the pipe H, is connected asmall escape pipeprovided with a suitable valve QI. As shown, this is a turn` ing-plugvalve, having a stem t" extending up through the cover and providedabove the cover with a small operating lever J. Upon the upper end ofthe pipe H just above the cover, the spout K is connected by a vswingingjoint k in such a manner that it may be placed at any angle with the topof the can. The spout consists, as shown, of two sections, k and lo, theoutward section k being smaller in diameter and sliding Within thesection 7o telescopically. The outer end of the section k is providedwith a bushing m, and the inner end of the section k is provided with acollar m which engages with the bushingm and prevents the sections frombeing pulled apart. In order to prevent'any leakage, I place a packingnut m upon the outward end of the section k.

For cans for some particular purposes, such as oiling shafting and othermachinery for which step ladders now have `to be used, I propose to uselong spouts composed of sev-` eral sections, but to illustrate myinvention, the two sections shown in the drawings will be sufficient.Upon the end of the outer section is a sleeve n by means of which thenozzle N is detachably connected to the spout. I find it advantageous tohave a detachable nozzle, for the reason that this piece is very muchecposed and liable to become bent or to be collapsed or broken. By theconstructiontshown the old one may be quicky removed and a new onereplaced without disturbing the remainder of the can.

In the upper part of the pump cylinder C are one or more perforations 0which permit any oil that leaks past the piston to escape from the upperside back into the rese IOO ervor. The perforations c also serve as aninlet for air from the hole c through which the piston rod passes, thishole being purposely made larger than the piston rod to serve as a vent.

In using an oil can with a pump it is important that the can should bekept in a vertical position at all times so that thepump valves will notbecome disarranged and for the further reason that the inlet or suctionpipe is always at the bottom of the can and it is necessary to keep itcovered with oil in order to have the pump operate satisfactorily. Bythe use of my jointed spout which may be thrown into a horizontal orinclined position while the can is vertical, I am enabled to reach allparts of the machinery without tipping the can. When the can is beingused the valve/L' in the escape pipe should generally be closed. Byleaving this valve more or less open the amount of oil discharged by astroke of the piston may be regulated, as the excess will be returnedthrough the drainage or regulating valve to the can. It', however, it isdesired to shorten the spout, this is done by placing a inger on thenozzle, and then pushing the sections together, the escape valve z'first being opened so that the excess of oil in the spout may be forcedback into the can. Again, when the can is out of use, the escape valveshould be opened so that the oil will all drain back into the can.

By the use of my improved can I have found it practicable to deliver oilto bearings in any position in the quantities desired, and without anywaste. The discharge is positive and the amount is easily regulated bythe distance the piston is pressed down.

It will be evident that 'various minor changes in location andconstruction ot parts may be made without departing from the spirit ofmy invention. Thus, for instance,

the pump cylinder might be placed upon the outside of the can, and thepipes and valves upon the inside, the bottom of the pump being simplyconnected to the inside by a single pipe, or the pump and the pipesleading to and from it may be placed outside of the can, the lower partof the suction pipe being connected with the bottom of the can, and

`:the drainage pipe being connected with the upper part of the can. Iprefer, however, the y l construction and arrangement shown in thedrawings, although I do not care to limit my claims to such constructionand arrangement precisely as shown and described.

1. In an oil can the combination with the spout having a slidingextension, of a drainage valve and means for opening and closing thesame, whereby the spout may be shortened and the expelled oil deliveredto the can, substantially as described.

2. In an oil can the combination with the body having a handle, and withthe spout, of a pump for supplying oil to the spout, the piston rod ofsaid pump extending upward `and having a thumb-piece at its upper end
